What are the differences between these sealers: S-B-S Sealer, Penetrating Paver Sealer, Porous Stone Sealer, Mexiglaze?
When you read the pages for each product in you will see very similar characteristics. The real difference is in the level of solids content for each.
S-B-S Sealer, Penetrating Paver Sealer, Porous Stone Sealer and Mexiglaze are in the same family of sealers and can be used over or under each other.
“S-B-S Sealer” (http://aldonchem.com/pr-sbs-sealer.htm) is the lowest solids level of the three. It is used on porous surfaces when little or no gloss is desired, but is designed for dense, low absorption surfaces where you need maximum penetration. A higher solids product will tend to penetrate less and leave more solids on top and that is what creates the gloss.
“Penetrating Paver Sealer” (http://aldonchem.com/pr-penetrating-paver-sealer.htm) is higher in solids than SBS Sealer but not as high as Porous Stone Sealer and is usually recommended for driveway type pavers.
"Porous Stone Sealer" (http://aldonchem..com/pr-porous-stone-sealer.htm) is the mid-range of solids content. For surfaces with a medium to high absorption rate.
"Mexiglaze" (http://aldonchem.com/pr-mexiglaze.htm) is the highest level of solids content. For surfaces that have an extremely high absorption rate.
One of the considerations is that a porous surface will absorb more sealer of a lower solids content, therefore, the higher the solids content - the fewer gallons required. However, it is best to not use a solids content level so high that it does not penetrate down into the surfacing. You want to achieve deep penetration with whichever sealer you use.
You can order samples to help decide which is best for your goals.
If you start with one of these sealers and decide the solids level is too high or too low, you can:
